ScentLok has updated its Climafleece base layers to emphasize warmth from less fabric while remaining light and mobile. A polyester face, stretch areas, fewer flat-lock seams, microfleece lining and wicking treatment support layering, fit and moisture control, and every men's and women's piece includes Carbon Alloy, Fusix and Silver Alloy odor technologies. Dedicated women's cuts plus crew tops, bottoms and a hooded option complete the line.
